c、选择添加页。 在这个页面上添加三个页面我们后面会在项目中用到
3、在ViewModels下的MainWindowViewModel中添加如下代码为每个页面定义导航命令。
public class MainWindowViewModel : INotifyPropertyChanged{private Frame _frame;public event PropertyChangedEventHandler PropertyChanged;
public MainWindowViewModel(Frame frame) {_frame frame;}/// summary/// 跳转到TaskPage/// /summaryprivate ICommand _navigateToTaskPageCommand;
public ICommand NavigateToTaskPageCommand{get{return _navigateToTaskPageCommand ?? new RelayCommand(param NavigateToTaskPage());}}/// summary/// 跳转到QueuePage/// /summaryprivate ICommand _navigateToQueuePageCommand;
public ICommand NavigateToQueuePageCommand{get{return _navigateToQueuePageCommand ?? new RelayCommand(param NavigateToQueuePage());}}
protected void OnPropertyChanged(string propertyName){PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));}
private void NavigateToTaskPage(){_frame.Navigate(new Uri(Pages/TaskPage.xaml,UriKind.Relative));}
private void NavigateToQueuePage(){_frame.Navigate(new Uri(Pages/QueuePage.xaml, UriKind.Relative));}
/// summary/// 登录之后用户名/// /summarypublic string? UserName{get{return UserInfoService.USER_NAME;}
}}
}
4、在MainWindows文件的Cs文件里修改代码如下
/// summary/// MainWindow.xaml 的交互逻辑/// /summarypublic partial class MainWindow : Window{public MainWindow(){InitializeComponent();DataContext new MainWindowViewModel(this.MainFrame);this.Loaded MainWindow_Loaded;}
private void MainWindow_Loaded(object sender, RoutedEventArgs e){MainFrame.Navigate(new Uri(Pages/MainPage.xaml, UriKind.Relative));}}
一个小作业
[!IMPORTANT]
如果有很多窗体也要一个一个这样写吗可以使用参数来处理。大家可以自己写一下。
